CHURN.

SPECIFICATION forming part of Letters Patent N 0. 708,665, datedSeptember 9, 1902. Q

Application filed May 29,1902. Serial No. 109,523. (No model.)

T0 at whom, it may concern:

Be it known that we, JULIAN BUFORD RIG- United States, residing atOlarksville, in the. county of Mecklenburg and State of Virginia, haveinvented certain new and useful Improvements in Chorus; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same. 1

The invention relates to improvements in churns, and particularlyto theclass of vertically-reciprocating single-dasher churns.

The object of the invention is to producea churn of the characterdescribed which will be light and easy of operation and by which thedasher will always be caused to reciprocate perpendicularly and true andwhich shall be simple of construction, durable in use, and comparativelyinexpensive of production.

A further object is to combine with the churn a fan adapted to be drivenby the same mechanism which drives the churn, the object of the fanbeing to drive dust, insects, and the like from proximity to the mouthof the churn.

With the above and other objects in View, the nature ofwhich will morereadily appear as the invention is better understood, said inventionconsists in certain novel features of construction and combination andarrangement of parts, which will be hereinafter fully described, definedin the appended claim, and illustrated in the accompanying drawings, inwhich- Figure 1 is a front elevation of the churn. Fig. 2 is a sideelevation thereof. Fig. 3 is a horizontal sectional view of the same onthe line 00 a: of Fig. 1.

In the drawings, 1 denotes a base which is preferably formed of slats.

2 denotes standards rising from the sides of. the base 1 and suitablybraced thereto by the inclined braces 3. The upright standards 2 areconnectedtogether at their upper ends by a cross-bar 4..

5 denotes the churn-body, which is adapted to rest upon the slatted baseand to be secured thereon by means of clamps 6, which engagethe slatsforming the base. The clamps 6 .rods 20, which are connected at theirarms 8, which are adapted to slide in guideloops 9, fixed on the ends ofbrackets 10,bolted to the standards 2. The arms 8 are held in anyadjusted position on the brackets 10 by means of set-screws 12, passingthrough threaded apertures in the guide-loops and impinging upon thearms 8. The inner ends of said arms are provided with segmental clamping-jaws 13, which are adapted to engage the upper part of thechurn-body and firmly hold the same against sidewise movement. Thus itwill be seen that the churn-body may be centered and securely held inany adjusted position. v

14 denotes the dasher-rod adjustably secured near its upper end to ahead 15, fixed on a cross-bar 16, the outer ends of which are bent atright angles to the length thereof and are adapted to slide in groovesor ways 17, formed on the inner sides of the standards 2.

18 denotes a crank-shaft journaled in bearings on the standards 2, nearthe upper ends thereof. The shaft 18 is provided with crankarms 19 ateach end adjacent to the inner sides of the standards 2, and to thesecrankarms are connected the upper ends of-pitmanlower ends to thecross-bar 16.

21 denotes a master gear-wheel journaled in bearings formed on one ofthe standards 2 and-in a bracket 22, fixed to said standard, as shown.The gear 21 is in mesh with a spur gear-pinion 23, fixed on the end ofthe crank-shaft 18. gear 21 is extended a slight distance beyond thebearing-bracket 22 and is provided with a crank-handle for operating thesame, so that when said handle and master-gear are rotated the pinion 23and the crank-shaft 18 will be driven and a reciprocating motion will beimparted to the churn-dasher through the me dium of the pitman-rods 20and cross-bar 16.

24. denotes a fan-casing adjustably mounted on a bracket or support 25,fixed to the rear side of the standards, and 26 denotes afanshaftjournaled in adjustable bearings mounted on arms or brackets 27,projecting rear- The'journal of the masterwardly from said standards 2.The shaft 26 extends through the casing 24 and has mounted thereon arotary fan. The discharge end of the fan-casing is provided with twoopenings 28, through which the blast from said fan is directed justabove the top of the churn on each-side of the dasher-rod.

29 denotes a small belt-pulley fixed on one end of the fan-shaft, andsaid pulley is connected by a belt 30 with a drive-pulley 31, fixed onone end of the crank-shaft 18, to rotate therewith, and thereby drivesaid fanshaft and fan through the medium of the beltpulley 29 and belt30.

The fan-casing is adjustable to and from the churn-body, as shown, topermit the use of different-size churns, or it may be removedaltogether, if desired. The dasher-rod 14 being adjustable in the head15 permits the dasher to be raised or lowered to churn as large or smalla quantity of cream as desired. The adjustable clamp for holding thechurnbody will permit the use of different-sized churns and will enablethe device to be used in connection with the old-style hand-dashers orany churn using a vertical dasher-rod, and while we have shown anddescribed the device in use with a single-dasher churn it is obviousthat the same may also be used in connection with vertical double-dasherchurns with but slight modification of the connections.

From the foregoing description, taken in connection with theaccompanying drawings,

it is thought that the construction, mode of operation, and advantagesof our improved churn will be readily apparent without requiring a moreextended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described our invention, What we claim as new, and desire tosecure by Letters Patent, is-

In a churn, a supporting-frame, a churnbody carried thereby and having areciprocating dasher, rearwardly-projecting bearingbrackets fixed tosaid supporting-frame, a transversely-disposed horizontal shaftjournaled in bearings adjustably mounted in said bearing-brackets, a fanfixed to said shaft, a

shelf or bracket carried by the supportingframe, a casing slidablymounted upon said shelf and inclosing said fan, and havingdischarge-openings arranged to direct a blast of air upon the top of thechurn, and gearing for reciprocating the dasher-shaft and driving thefan-shaft, substantially as described.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
